Description
Technical field
The utility model belongs to groundwater treatment equipment technical field, especially for the stake device of processing the regeneration reducing agent of groundwater azotate reaction material.
Background technology
The dielectric material of removing for groundwater azotate pollution generally comprises the zero-valent metal (the modal FeO of being) with extremely strong reducing power, and activated carbon, ion exchange resin, phosphoric acid salt and some natural materialss are as chitin, zeolite, Wingdale, organic clay etc.Have plenty of the material for laboratory, some use is the reparation of underground water at the scene.The main component of these materials generally adopts iron powder.According to research, and nitrate radical reacts is mainly Fe
2+, but be subject to materials'use to count the restriction in quantitative limitation and work-ing life, Fe
2+reduce gradually, the ability that correlation combiner material is removed nitrate also reduces gradually.Relevant underground water recovery project result shows, the work-ing life of general underground water recovery project is in 7～10 years, after surpassing work-ing life, and Fe
2+also be reduced into gradually high price iron (Fe
3+) and lose response capacity, in the world, generally, after dielectric material lost efficacy, again replace, will expend a large amount of manpowers, financial resources and material resources like this.In laboratory, utilize reductive agent that iron powder is reduced to process and make Fe
3+be reduced into Fe
2+have certain research, but field Project Realization is more difficult.
Summary of the invention
The purpose of this utility model is to provide a kind ofly can carry out to removing nitrate reaction material the stake device of the reductive agent of on-the-spot extensive reduction.This device can be applicable to take FeO as main medium, and structure formation is the stake of regeneration reducing agent of original position repair system of the underground water of continuous body of wall, channel-type, well construction.The purpose of this utility model takes following technical scheme to realize: a kind of stake device of the regeneration reducing agent for the treatment of groundwater azotate reaction material, it is characterized in that: this device is provided with casing pipe, on casing pipe, have treatment hole, intrusion pipe is installed in casing pipe, and the bottom of intrusion pipe is provided with block head shutoff; Intrusion pipe bottom is drilled with slurry outlet, on intrusion pipe, be provided with mounting flange, on mounting flange, on intrusion pipe, be installed with elastic caoutchouc ball, above elastic caoutchouc ball, be provided with loose flange, above loose flange, on intrusion pipe, clamp sleeve is installed, clamp sleeve is enclosed within the outside of intrusion pipe, the top of clamp sleeve is provided with hold-down nut, and perfusion is provided with screw thread, rotatably compresses nut, under the effect of clamp sleeve, compress elastic caoutchouc ball, rubber sphere transverse deflection expands.
